IMPROVEMENT IN APPARATUS FOR UTILIZING WASTE GASES 0F DISTILLATION IN REFINING PETROLEUM.

To all whom it may concern:

e it known that I, HENRY E. PARSON, of the city, county, and State of New York, have When the injector is at work the waste gases of distillation that collect in the main pipe and chamber are drawn into the injector by the steam-jet.

The main pipe A has a second gas-chamber or receiver, B, at some distance from the first chamber, B, which second chamber is connected by a pipe, 0, with a storing and distributing tube, E, and by a pipe, 0 of the storing and distributing tube with the atmos phere.

The second receiver, B, and pipe 0 admit of the escape of the oil-vapors, whenever the following is a specification.

In the accompanying drawings, Figure 1 represen s a sectional side elevation of a still for refining petroleum, shown as arranged with my improved attachment for utilizing the waste gases of distillation. Fig. 2 is a front view of the furnace, partly in section through the injector on line as m, Fig. 1, showing the adjustable covers around the air-supply opening; and Fig. 3 is a detail section of the oilpipe and gas-receiver. Fig. 4 is a front View, in which the storing and distributing pipe and its connections are shown in longitudinal elevation.

Similar letters ofreference indicate corresponding parts.

The object of this invention is to utilize the gases that are formed in the process of distilling petroleum after the oil leaves the condensing-coil. A second receiver and escape-pipe a number of stills, and connected with the escape-pipes of the different oil-pipes of the same. The waste gases are thereby stored up in the tube, and made available for the inthe storing and distributing tube is too large, they pass through the exit-pipes 0 off into the atmosphere. When the injectors have drawn off all the vapors stored up in the tube atmospheric air is drawn in, which mingles with the gases or vapors drawn off from the and distributing tube, that connects the esmain pipe, and is forced with the same by cape-pipes of the different stills, the storing the injector into the fire, so as to be fully conand distributing tube being connected with sumed therein. the atmosphere to discharge the surplus gas, The opening in the furnace-wall through and also to draw in air to mingle with the which the injector is inserted may be partly waste gas, and be thrown therewith into the or entirely opened or closed by means of pivfire. oted or otherwise adjustable doors F, which Referring to the drawings, A represents the regulate the supply of air that is drawn into main oil-pipe, which conducts the oil from the the fire-place in proportion to the quantity of condensing-coil of a still to the receivinggas fed to the fire, so as to produce thorough tank.

In place of the two gas-chambers B and B, An enlarged gas chamber or receiver, B, is one chamber only may be used, and the returnarranged at one end of the enlarged section pipe and escape-pipe applied thereto; or the of the main pipe, and connected by a pipe, escape-pipe may be made to branch off from G, with an injector, D, that is arranged in the return-pipe, the operation in all casesbefront of the fire-place, for the purpose of ining the same. creasing the heat of the fire by a supply of oil- The same apparatus may also be applied for vapor and steam, properly mingled with air. utilizing the waste gases of oil-wells, the well- 2 214,946 I f t casing and pump being then, in place of the condenser, connected to the apparatus, and then conducted to a furnace.

I am aware that it is not new to heat stills for distilling petroleum or hydrocarbon oil by the gas evolved from the petroleum during the process of distillation, or to relieve an oil-still of its gas and inflammable products by means of currents of steam acting on the gas for the purpose of drawing the gas from the still and forcing it into the furnace with the steam to be burned and utilized; but What I claim as new and of my invention 1s- The combination of an oil-pipe connecting the condensing-coil and receiving-tank, and of an injector of a petroleum-still, the oil-pipe having one or two gas chambers or receivers, with a gas-returning pipe and with a gas-escape pipe, storing and distributing tube, and exit-pipe opening into the atmosphere, substantially as shown and described.
